In a video posted to Twitter Monday, the president of France tore into a teenager who called him 'Manu,' a common nickname for Emmanuel in French, during an event at a World War II memorial.
Instead of shaking the boy's hand, or taking a selfie — as he did with other crowd members, Macron proceeded to reprimand him.
"Call me 'M. President of the Republic' or 'Sir'," Macron said in the video.
He also tweeted his disapproval citing the boy's lack of respect.
